We need to calculate the internal gas pressure when the gas tank is heated or cooled (not provided in the question). Let's say that final temperature of the tank and its contents is Tfinal.

p*V = n*R*T, R is the gas constant and V is constant because gas tank volume is constant

then p/T is constant

then pinitial/Tinitial = pfinal/Tfinal

then 10/300 = pfinal/Tfinal

and pfinal = Tfinal*10/300, if we know Tfinal we will know pfinal.

Q.2 For the nitrogen molecule, calculate the following: i) Translation energy per molecule at 300K ii) Translation energy per mole at 300K iii) Number density at 298.2K iv) Concentration at 298.2K

KE per molecule = 3/2 kT = 3/2 * 1.38e-23 * 300 = 6.21e-21 (J) KE per mole: 3/2 RT = 3.74 kJ In the next calculations, it is suggested...

.600g of solid CO2 is put in an empty sealed 4.00L container at a temperature of 300K.When all the solid CO2 becomes gad, what will be the pressure in the container?

no of moles of CO2 = .600/44.01 = 0.0136molPV = nRTP × 4 = 0.0136×0.0821 × 300P × 4 = 0.335P = 0.08375 atm

A vessel of 2×10⁻³m³ volume contains 0.036 kg of Argon at 300K. Calculate its pressure using ideal gas equation. ( Atomic mass of Ar = 39.9u).

V= 2x10-3m3 = 2dm3m= 0.036Kg = 36gT= 300KR= 0.0821L.atm/k.molnumber of moles, n= mass/Molar mass = 36/39.9= 0.9molPV= nRTP= nRT/Vp= 0.9x0.0821x300/2P= 11.08atm

A sample of gas at 300 torr inside a steel tank is cooled from 500 °C to 0 °C. What is the final pressure of the gas in the steel tank? (round to one sig fig)

P1/T1=P2/T2T1 = 500 + 273 = 773KT2 = 0 + 273 = 273K300/773 = P2/273P2 = 106 torr

a steel tank contains 15.0 g of cl2 gas under a pressure of 5.0 atm at 22.0 degrees c what is the volume of the tank

P = 5.0 atm;T = 22.0 °C = 295.15 K;M(Cl2) = 70.906 g/mol;n=m/M;n(Cl2) = 15.0 g / (70.906 g/mol) = 0.211 moles;Ideal gas law: PV=nRTV = (nRT)/PMolar gas constant R=0.082058...

If you have a gas at 300K and 1atm of pressure, and then you drop the temperature to 225K, what will the new pressure of the gas be?

p1/T1=p2/T2;p2=p1*T2/T1=1*225/300=0.75 atm;Answer: 0.75 atm

One mole of a perfect gas at 300K has an initial pressure at 15 atm and is allowed to contract isothermally to a pressure of 1 atm. Calculate the entropy change from this contraction

Initial pressure=15atm,final pressure=1atmTemperature=300kNow 1Latm= 103joules∆dsystem=∆dsurrounding=-(dv)/T={-(15-1)/300}×103=-4.80J.

An LPG tank contains 11.0 kg of butanr gas (C4H10) in a 20-L gas tank. What mist be the Pressure of the gass inside the tank when the Temperature is 27°C?

No of moles= mass / molar mass = 11000/58 = 172.4molesPV=nRTP = nRT/VP= 172.4 × 0.0821 × 300 / 20P= 212.3atm
